Thin-Layer Chromatography of Metal Ions Complexed with Anils (V). Detection,Separation and Determination

Abstract

p-Diethylaminoanil of phenylglyoxal a bidentate ligand was used for complexation with Hg(II), UO₂(II), Au(III), Pt(IV) Mg(II), Bi(III), Sb(III) and Be(II) ions. The chelates were characterized by their analysis, molar conductance and infrared spectra. T.L.C. detection, separation and determination of these complexes on starch bound silica gel layers was studied Long persisting dark coloure of the complexes rendered the spots self descernible and no locating agent was required. A maximum four complexes could be resolved and identified. Errors in determinations and maximum separation limits were also deduced.
